The
Walletexplorer.com can help you out. But there is prerequisite to use it. The address you use to discover a corresponding wallet has had at least one transaction. If there is no transaction has been made on that address, the site can not help you.
If you know some addreses and think they are belong to one wallet, you can enter those addresses to the site and search. If they are belong to same wallet, you will see results from the site with same wallet ID.
As far as I know wallet explorer only works if you connect your address. For example, you have two different inputs on two addresses. You have sent them into one address. This way, both addresses have been connected and wallet explorer can give that information. On the other hand, if you do mot connect the addresses, wallet explorer will not recognise them. Tell me if I am correct or wrong.
